8.132. PRESETL -- List All Commmands in a Preset
This command lists all the commands in a given preset. For example, assume that user preset 18 has
been defined previously by the following command.
S01PRESETW18
Now, issuing the command:
S01PRESETL18?
Will result in a long sequence of status mesages reflecting all the data stored in the preset. At the end
of the status messages, a final message of
S01PRESETL18
will be displayed.
8.133. PRESETP -- Set Which Preset Will Be Activated At
Power-Up
This command sets or queries the power-up preset, which is executed each time the device powers
up. The power-up preset must be one of the factory presets (0-15) or one of the user presets (16-47).
This command is saved to global non-volatile memory and is not part of a preset. Its value is saved
each time it is changed. It will retain its value after power-down. Since this command writes to non-
volatile memory, there will be a delay before an acknowledgment is returned.
